Numbers 5:2-4
2
"Command the children of Israel that they put out of the camp every leper, and everyone who has an issue, and whoever is unclean by the dead.
3
Both you shall put male and female outside of the camp; that they not defile their camp, in the midst of which I dwell."
4
The children of Israel did so, and put them out outside of the camp; as Yahweh spoke to Moses, so did the children of Israel.
